I\'d like to deploy a background image in the body of my website that scales down with the window resolution, but does not scale up beyond it\'s original size (1920x1080). T
Just a really small/quick suggestion:
Depending on how it looks, and all flows together, background-size:contain; might be an option.
background-size:contain;
or, on your body, set the max width to 1920, set the margins to auto, and that might also work for you.
